To evaluate:
The value of the given number
Answer to Problem 20WE
The value of given operation is satisfied the equation
Explanation of Solution
Given:
The equation
Concept used:
Replace the inequality sign and sketch the graph of the resulting equation (use a dashed line for < or > and a solid line for
Test one point in each of the region formed by the graph
If the point satisfies the inequality then shade the entire region to denote that every point in the region satisfies the inequality
Calculation:
The order of operation
This equation is true
Therefore,
The value of given operation is satisfied the equation
